Anticipated Surface Pressure:3,171 psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:1,950psi (stacked out lift gas) (Taken on 5/3/23) Min ID:1.875” - nipple reducer at 18,813’ Max Angle:70.71 Deg @ 16,750’ Brief Well Summary: L5-34 is a Niuakuk Kuparuk producer drilled from L5 drillsite. The well currently produces at low fluid rates causing it to hydrate off and struggle with on time. Objectives: The objective of this procedure is to addperf/reperf additional pay to increase total fluid rates enough to keep the producing temperature gradient outside of the hydrate window. Procedure: Coiled Tubing Notes: x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. 1. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through the brass upon POOH with guns. 2. Bullhead ~370 bbls (1.2x WBV) of 9.0ppg brine down tubing. Max tubing pressure 2500 psi. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.) a. Wellbore volume to bottom perf = 306 bbls b. 4-1/2” Tubing – 18,824’ x 0.0152 bpf = 286 bbl c. 7” Liner – (19,351’ – 18,824’) x 0.0371 bpf = 20 bbl 3. MU and RIH with logging tools. Flag pipe as appropriate per WSS for perforating. 4. POOH and freeze protect tubing as needed. Confirm good log data. 5. At surface, prepare for deployment of TCP guns. 6. Confirm well is dead. Bleed any pressure off to return tank. Kill well with 9.0 ppg brine as needed. Maintain hole fill taking returns to tank until lubricator connection is re-established. Fluids man- watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. Well: L5-34 PTD:198-0850 API:50-029-22883-00-00 7.*Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. a.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 8. Break lubricator connection at QTS and begin makeup of TCP guns per schedule below. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. Perf Schedule *HES 1.56” guns were used to estimate for this job and calculate gun weights.

Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 13.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, AP! and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Mehreen Vazir, at 659 -5102. Sincerely, Gerald Murphy BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

As the attached AOGCC BOPE Test Report shows the test lasted 3 hours with no failures. The test of the Blind rams, Annular Preventer and the Kelly valves was not witnessed this evening due to a mechanical problem with the test pump, but were tested later by toolpusher John West. The rig was clean and all equipment appeared to be in good working order. The location was clear and all excess equipment was properly stored.

The maximum anticipated reservoir pressure is 4500 psia @ 9200' TVD, this was original reservoir pressure. Expected reservoir pressure is 3,900 psi @ 9200' TVD. Lost Circulation/Faults 1. The Niakuk bounding fault is expected to be crossed in the Ugnu section. Well path must avoid Ivishak and Lisburne on the upthrown side of the Niakuk fault. These horizons would contain high pressure gas from offset injection. Close Approaches Close approach issues are minimal. L5-32 and L5-36 pass all appropriate Anti-Collision policies. Formations ~ Expect to have full sections of Colville and HRZ shales. Both formations have shown sticking potential in the past. Mud weight will be increased and shale stability treatments will be performed as needed. Well Control: Well control equipment corisisting of 5000 psi WP pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.

THIS LOG IS THE PRIMARY DEPTH CONTROL. This file also contains the Very Enhanced QRO resisitivity with 2' average that was reprocessed at GeoQuest. The ADN quadrant outputs are as follows: ROBB/ROBU/ROBL/ROBR are bottom, upper, left, and right quadrant density; and are also listed as RHO1, RH02, RH03, RH04 in the LDWG listing. The other outputs (Delta Rho, PEF) are listed with their quadrants as DRHB/DRHU/DRHL/DRHR, PEB/PEU/PEL/PER. The LDWG outputs of CALA and CALS are ~{DIA and VDIA respectively. $ $ PAGE: **** FILE HEADER **** FILE NAME : EDIT .001 SERVICE : FLIC VERSION : O01CO1 DATE : 98/08/21 MAX REC SIZE : 1024 FILE TYPE : LO LAST FILE : FILE HEADER FILE NUMBER: 1 EDITED MERGED MWD Depth shifted and clipped curves; all bit runs merged.
